Beginner wise Glendo is a good spot but I can't help feel that the presence of other boulderers and problems sometimes derails their efforts to try stuff of the right level. Most of the other areas in Wicklow aren't really suited to beginners, the only one that is I think is Carrigshouk, there are some nice, easy, low problems very close to the road. I climbed a few problems on the two white rocks right beside the parking and they are great. Plenty more like that. I think it might be worth giving a page or two to describe them, do you think people will bother to seek them out though or will they just head to glendo?
Alot of the posts are quite Wicklow-centric at the moment but thats just the way it is.
